How to calculate your solar power requirements: There are three things to consider in order to choose a Solar panel or create a Solar system. You need to know how much energy your battery can store and then select a Solar panel that can replenish your ‘stock’ of energy in the battery in line with your pattern of use.
Battery life and low power consumption are ongoing concerns of modern battery-powered electronics. Estimating them at the beginning of a design process can be quite challenging. Indeed, battery life and power consumption depend on almost all of the device characteristics: its hardware, battery, firmware, use case, and its environment.
Step 1: Collect the Total Connected Loads The first step is the determination of the total connected loads that the battery needs to supply. This is mostly particular to the battery application like UPS system or solar PV system. Step 2: Develop the Load Profile
Maximum Battery Power: This depends on the number of battery cells in your setup. Once you have this information, use the following formula: Batteries needed (Ah) = Daily consumption (Ah) X Backup days X Annual correction factor 1.15 / DOD (%).
Overall, the average error made on battery supply voltage estimation is 6.17%. Regarding battery life accuracy, we observed results between 88.44% and 103.25% of the real battery life with an average error of around -6.93%. The presented simulation tool, its power consumption and battery life analysis are available in the feature “Power Analysis”.
